Notes
  1. Inductance is for the secondary, measured at 15.75 kHz, 1 Vrms.
  2. DCR at 25°C, For other operating temperatures,use this DCR at Temperature calculator.
  3. Volt-time product is for the secondary, between pin 1 and 4.
  4. Terminating resistance (RT) value is based on 1 Volt output with 35 Amps flowing through the primary. Varying terminating resistance increases or decreases output Voltage/Ampere according to the following equation:
    RT = Vout × Nsec / Iin.
  5. 3750 Vrms, one minute winding to winding isolation (hipot).

Termination:

  • RoHS-compliant. Tin-silver over copper terminations.
